WINDOW- CATCH.

Application filed December 13, 1922. Serial No. 606,751.

Toall whom it may concern."

Be ,it known that I, SAMUEL R. WALLEN, a subject of the King of Great Britain, residing at Chase, in the Province of British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Window Catches, of which'the following isa s ecification.

M invention relates to improvements in win ow catches, and has for an object to provide a sash fastener ofthe type applied to the upper sash of a, window and having means for engagement of the meeting rail of the lower sash whereby both of the sashes are held from movement other. 7

A further object of my invention is to provide a sim le, double sash box, capable relative to each of holding bot upper and lower sashes in a closed position and adapted to be applied to the ordinary window sashes with a minimum of structural alteration or modifications thereof, without the necessity of employing skilled labor.

still furtherobject of my invention is to provide a window lock, that is positively guarded against accidental displacement or oroible unlocking-of the samefwhen the catch is locked. A A still further object of my invention is to provide a vwindow lock, t at is simple, strong, durable and inexpensive in construction, and that is well adapated to the use for which it is designed.

"Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts throughout the same, v 1

Figure 1 is a perspective view of the apparatus in its assembled condition, when applied to the ordinary window sashes in a locked position,

'Fi m2 is a top plan view of the same part y in section for the purpose of illustration, and v nates an ordinar -window casing having the Figure 3 is a longitudinal section taken through the same.

the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 desigusual upper sas 6 and the lower sash 7.

the upper rail 0 P a y sash 7 and held a transverse bar 12 is the notch 13 is in such a positionthat the be swung upwardly, I

f fore, when the'catch means of suitable screws 9. The late 8 may be the same length as the width of the lower sash, as is clearly shown in the drawings, and a plate'lO is hinged to the fixed plate S by means of a hinge 11.,

A transverse bar 12 having a notch 13 is mounted within the guide members 14 which are carried by the fixed plate 8 on the upper sash. The transverse bar 12 is provided on its inner edge with a beveled face 15 throughout its entire length thereof.

-Mounted approximately midway of the end of the pivoted plate 10, are a pair of spaced ears 16, to which is pivoted an arm 17 by means of a bolt or the like 18. A knob 19 is mounted near the upper end of the plate 10, to operate said plate. As is clearly shown in the drawings, the upper sash 6 is provided with a recess 20 which is surrounded by a-metallic plate 21 which is held in place by means of suitable screws 22. A button 23 is mounted "on the back of the plate 10 and is adapted to be received in the cutout portion 20 in the upper sash 6.

It will thus be seen in-use, that the plate 8 is mounted on the upper rail of the lower in place by the screws 9. When it is desired to lock the sashes against movement, the transverse bar 12 is slid through the guide members 14 until the notch 13 is directly opposite the arm 17. The pivoted arm 17 is then swung down into position being seated in!" a recess 24: within the plate '8, and the uransverse bar 12 is slid to the left, the beveled/face 15 riding over he side of the pivoted"; arm 17, and .firmly hold the arm 17 against displacement. It will also be seenithat the button 23 within the recess 20 positively prevents movement of the sashes within the casing 5. When it is desired to raise or lower the sash, slidto the right until ivoted arm 17 may in which position the knob 19 may be pulled down thereby releasing the button 23 from the cutout portion 20 within the sash. In Figure 3 of thedrawings, the position of the catch in its inoperative. osition is clearly shown in dotted lines. t will readily be understood, that the pivoted arm 17 forms an'additional' support and catch and is used in conjunction with the button 23. Thereis in a position as is clearly shown in Figure 2 ofthe drawings, I

there is no possible way in which a person from the outside can release the lock with out breaking the window pane or sawing through the button 23.

It is to be understood that the form of mv invention herewith'shown and described is to be taken as a'preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the sub'oined claims.

aving thus described my invention, I claim:

1. In combination with a window including an upper and a lower sash, said upper sash being provided with a recess, a. window catch comprising a base plate mounted on said lower sash, a plate hinged to said base plate, a button mounted on the back of said hinged plate adapted to be received within said recess in said upper sash, an arm pivotally connected to said hinged plate, and means tohold said pivoted arm rigid.

In combination with a window including an upper and a lower sash, a window catch comprising a base plate mounted on said lower sash, a plate hinged to said base plate, a pair of spaced ears carried by said hinged plate, an arm pivotallyconneoted between said ears, a transverse locking bar mounted on said base plate, said bar adapted to be abutted by one end of said arm for holding the hinged plate in association with the upper sash, and guide members for said '35 transverse locking bar. I

3. In'combination with a, Window including an upper and lower sash, said upper sashbeing provided with a recess, a window catch comprising a base plate mounted 40 on said lower sashya plate'hinged to said base-plate, a button mounted on the back of said hinged plate and adapted to be received within said recess in said upper sash, an arm pivotally." connected to saidhinged plate, a locking'bar provided with a notch mounted on said base plate, one end ofsaid arm adapted to be received in the notch of said bar for holding the hinged plate in a position whereby said button is disposed in said recess in the uppersash, and guide members for said locking bar. r
